A predictive study of emotional labor and turnover

The current study examined how the emotional labor strategies of deep acting and surface acting directly influence emotional exhaustion and turnover intentions, and indirectly impact actual turnover among a sample of bank tellers. Turnover data were collected from organizational records 6 months after participants responded to a survey that measured emotional labor strategies, emotional exhaustion, and turnover intentions. Results showed that turnover intentions mediated the relationship between deep acting and actual turnover. Additionally, surface acting had indirect effects on turnover through emotional exhaustion and turnover intentions. Copyright © 2009 John Wiley & Sons, Ltd.     

Radon risk assessment: The effect of voluntary sampling distributions and bias

This paper examines the problem of estimating indoor radon concentrations for radon-induced lung cancer risk assessment. Previous authors have identified various problems and possible corrections for the use of generally available radon screening measurements. Bias evident in data collected from volunteers is described; regional databases developed from voluntary data generally exhibit higher mean values than those obtained from random samples. Tools are developed to better characterize the differences in voluntary and random concentration distributions. Application is demonstrated using voluntary and random radon survey data for the state of North Dakota.     

Are all chromosome microarrays the same? What clinicians need to know

Microarray testing is the recommended first-tier diagnostic test for women who undergo invasive prenatal diagnostic procedures. It is well-established that microarray analysis provides information regarding copy number for changes (or copy number variants, CNVs) that may be below the resolution level of standard chromosome analysis, and that such CNVs are not related to maternal age. What may not be appreciated by ordering providers, however, are the technical differences among laboratories with respect to the established laboratory cutoff values for reporting, the definition of targeted versus nontargeted regions, and how these differences may affect the interpretation and reporting of findings which, in turn, affects counseling and possible follow-up testing of family members. Here, we provide a detailed explanation of these technical factors and clarify how they practically impact diagnostic results.
